Why do you rotate the backup directory? There is no need to rotate
directories in an rdiff-backup repository. You can recover previous
versions anyway. You can delete old versions if you need the disk
space back (but they are stored efficiently so it might not be
necessary).

We have been running

rotated each week, and last night the initial (full) backup
apparently failed.
